Abstract
L'invention a pour objet un dispositif d'absorption des chocs. Il comprend deux conteneurs 1A, 1B contenant un fluide et mis en communication par l'intermédiaire d'un passage étranglé 5 dans lequel est montée une membrane d'obturation susceptible d'être brisée quand la pression du fluide atteint une valeur prédéterminée; des pistons saillants 3A et 3B mobiles par rapport au conteneur 1A et 1B sont attelés respectivement par des tiges 11A et 11B à des organes susceptibles de recevoir les chocs à amortir. L'invention est utile principalement pour la protection des parties avant et arrière des moyens de transport.The invention relates to a shock absorption device. It comprises two containers 1A, 1B containing a fluid and placed in communication by means of a constricted passage 5 in which is mounted a sealing membrane capable of being broken when the pressure of the fluid reaches a predetermined value; projecting pistons 3A and 3B movable relative to the container 1A and 1B are respectively coupled by rods 11A and 11B to members capable of receiving the shocks to be damped. The invention is useful mainly for the protection of the front and rear parts of means of transport.
